SCOOP.

Application filed September This invention relates to scoops.

In cleaning the bottom of lakes adjacent the shores it has been found that no satisfactory type of scoop is available for this purpose which will at once be of simple and strong construction and also easy to manipulate and effective in operation.

This invention is designed to overcome the above noted defects, and objects of this invention are to provide a scoopwhich is of extreme simplicity and of great rigidity, which may be operated in a very simple manner to clean the bottom of lakes, and which will automatically ride over the ground or mud on the bottom of its out stroke and will scoop up and retain the mud on its instroke.

Embodiments of the invention are shown in the accompanying drawings, in which Figure 1 is a side elevation of one form of scoop showing in full lines its position on its inward travel, and in dotted lines the relative position of the parts on its outward travel. I

Figure 2 is a plan view of the structure shown in Figure 1.

Figure 3 is a front view partly in section of the scoop.

Figure 4 is a fragmentary sectional view of the device.

Figure 5 is a longitudinal sectional view showing a modified form of scoop.

Referring to Figures 1 to 4, it will be seen that the'scoop comprises a pair of sidemembers 1 which are joined by means of a back plate 2. This back plate slants downwardly and forwardly, as shown most clearly in Figure 1, and is preferably attached to the side members 1 by means of angle iron or other bracing members 3. The scoop is provided on opposite sides with a pair of angle irons or similarly bracing members 4 equipped with outwardly projecting stops 5 for a purpose hereinafter to appear.

The front of the scoop is provided with bracing angle irons 6 and a transverse upper bracing member 7. Preferably, the upper bracing member 7 is joined not only at its points of crossing to the angle iron 6, but also by means of the diagonal bracing members 9, as shown most clearly in Figure 3.

A bridle or cable 10 extends from opposite sides of the front of the scoop to the draft cable by means of which the scoop is pulled inwardly towards the shore. Prefers 26, 1925. Serial No. 5 8,839.

ably, a pair of eye bolts 11 are passed through the angle irons 3 at the rear of the scoop, as shown in Figure 4, and the cables 12 are secured to these eye-bolts, such cables passing to the cable for drawing the scoop outwardly into the lake.

In order to prevent the scoop from digging into the bottom of the lake on its outward travel, a pair of pivot runners or shoes 13 are provided on opposite sides of the scoop. These runners have upturned rear ends 14 and upwardly extending forward portions 15. The forward portions 15 are integral with each other and are joined by means of the transverse shaft 16, as shown most clearly in Figure 2. Preferably, the extreme rear ends of the shoes are joined by means of a channel member 17 and are locked thereto by means of U-bolts 18. The upturned rear and forward ends 14 and 15 of the runners are joined by means of the bracing member 19, as shown in Figure 1. 1

Other bracing means may be employed for the scoop, if desired, for instance an upwardly and forwardly extending bracing strap 20 may be bolted to the outer side of the members 1 and may join the channel irons 3 at the rear to the channel irons 6 at the front, thus increasing the strength of the device.

In using the scoop, it is intended that a cable pass outwardly into the lake and a cable extend forwardlyfrom the scoop to the shore so that the scoop may be drawn in either direction.

Vhen the scoop is drawn outwardly on its reverse stroke or travel, the runners or shoes rock into their dotted line position, as shown in Figure 1, and thus elevate the rear end of the scoop and cause it to ride over the bottom of the lake without disturbing the mud or sediment. However, upon the forward stroke or travel of the scoop, the runners rock into their full line position, as shown in Figure l, and allow the rear end of the scoop to rest upon the bottom of the lake. During its forward travel, the rear plate 3 scrapes up the mudor sediment and such material accumulates between the side members 1 and is drawn to the shore. A reverse direction of travel immediately elevates the scoop and causes the material to be quickly discharged upon the shore and also permits, as stated above, the free riding of the scoop outwardly upon the shoes, it

V of the lake.

being noted that the stops 5 hold the run ners in their correct position for the reverse travel of the scoop.

In the form shown in Figure 5 substantially the same inventive idea is disclosed. However, the side frame members 21 are provided with brackets or other supporting pivot members 22. Preferably, these pivot members are provided with a plurality of holes 23 into any one of which the arms 24: may be pivotally mounted to thus provide vertical adjustment.

In this form of the invention, the back plate is made of an upper portion 25 anda movable lower portion 26 carried by the arms 2%. Further, each of the side plates of the scoop is provided with an extended runner 27 which has upturned forward and rear ends 28. These runners at all times travel upon the bottom of the lake both for the forward and rear travel of the scoop. However the movable plate 26 of the back member rocks into the dotted line position shown in Figure 5 upon the reverse or outward travel of the scoop and thus does not dig into the mud or sediment at the bottom On the forward travel, the member 26 rocks into the full line position shown in the figure and scoops up the material. v

The member 26 may be adjusted vertically, as indicated, so as to adapt the scoop for a variety of conditions.

Although the invention has been described in considerable detail, it is to be understood that the invention may be variously embodied and is, therefore, to be limited only as claimed.

I claim:

1. A scoop comprising a body portion having side walls and an open front and bottom, means at the front and rear of the scoop for attachment to cables, a downwardly and forwardly slanting back plate closing the rear of the scoop during its forward working stroke, and means attached to the back plate and pivoted adjacent the upper rear portion of the side walls, whereby said back plate may swing bodily forwardly and upwardly completely away from the rear of the scoop during the reverse or retraction stroke of the scoop.

2. A scoop comprising a body portion having a pa r of side walls and a back digging plate, said scoop having cable receiving means attached directly to the front and rear of the body portion, and means pivotally carried adjacent the upper rear portion of the side walls and free from operative connection with said cables for elevating the back plate and raising such plate from digging position.

In testimony that I claim the foregoing I have hereunto set my hand at Oconomowoe, in the county of lVaukesha and State of lVisconsin.
